A CBZ file is basically a ZIP archive labeled as a comic, holding page images—usually JPG/JPEG, sometimes PNG or WEBP—named in numbered order like `001.jpg`, `002.jpg` to keep pages sorted, often including a cover image and optional metadata such as `ComicInfo.xml`; comic apps open it like a book with features such as zoom and page flipping, while you can extract the raw images by opening it with 7-Zip or renaming it to `.

A CBZ file being “a ZIP file with a comic label” states that CBZ is merely ZIP repurposed for comics, letting comic readers treat its contents—typically numbered JPG/PNG pages—as a book, while archive tools can open it normally if you rename it to .zip; the behavior difference comes from the extension, since systems rely on it to choose the appropriate app.
A CBZ and a ZIP can contain identical image sequences, with .cbz telling comic apps to present the content as ordered pages and .zip signaling a general archive; CBZ’s ZIP foundation ensures maximum compatibility, while its siblings—CBR (RAR), CB7 (7z), and CBT (TAR)—store images the same way but may have reduced support depending on compression type and platform.
In real-world terms, the “best” format comes down to seamless usability rather than technical specs, making CBZ a strong default thanks to ZIP’s ubiquity, while others work if supported; when opened in a comic reader, a CBZ becomes a flowing page-based experience with zoom and navigation, rather than a set of images you must extract manually.
A comic reader app “reads” a CBZ by opening the archive and identifying image pages, filtering out non-page items, sorting filenames into the correct order, and then selectively decompressing the current and upcoming pages to memory for fast navigation, applying your view settings (scrolling, zoom, spreads), remembering your last page, and creating a cover preview for the library interface.
Inside a CBZ file you typically find the comic assembled as a ZIP of numbered images, usually JPEG but sometimes PNG or WEBP, named with leading zeros for correct ordering; a cover image is often included, subfolders can show up, and metadata like `ComicInfo.xml` or stray extras might be present, yet the essential structure remains a straightforward, well-ordered image sequence inside one archive.
